grep*.deb is missing "Multi-Arch: foreign"

[Helm]

The grep package of Ubuntu 12.04 misses the line "Multi-Arch: foreign" in the "control"-file.

Without this line it is not possible to build packages depending on grep for the architecture i386 and to install this package on AMD64.

Thanks for your work on this. Unfortunately the precise debdiff has the following problems:
 * because this is a SRU, it needs to target precise-proposed, not precise
 * the version number should be 2.10-1ubuntu0.12.04.1 as per https://wiki.ubuntu.com/StableReleaseUpdates#Procedure
 * debian/changelog is too terse and doesn't explain why the change is needed

The quantal debdiff has the following problems:
 * because this will need an SRU, it needs to target quantal-proposed, not quantal
 * the version number should be 2.10-1ubuntu0.12.10.1 as per https://wiki.ubuntu.com/StableReleaseUpdates#Procedure
 * debian/changelog is too terse and doesn't explain why the change is needed

This should also be forwarded to Debian. Can you update the debdiff and resubscribe ubuntu-sponsors? Thanks!

[Jamie Strandboge (jdstrand)]

Whoops! I misread the versions. Please update them to have:
 * 2.10-1ubuntu0.1 for precise
 * 2.12-2ubuntu0.1 for quantal

grep is an essential package, which means other packages should not depend on it. Without a specific example of a package which needs a versioned dependency on grep and needs to be installed in a multiarch context, we should not make this change.
